Hello, I am plumbing out a seasonal cottage that needs to be winterized and I am considering the use of 2 Rheem 6kW tankless electric water heaters in parellel just to run the single shower in the cottage. The main reason I am considering this small heater is because the heating element in these is single and horizontal, it seems easy to be able to drain it for the winter. I have a brand new 200A service to the cottage so electrical draw is not a problem.
What are the main challenges with plumbing these tiny water heaters in parallel? Or do you have any other suggestions for a solution that can be drained for the off season (winterizing with antifreeze will be logistically very challenging).
Note that I have a separate (non-potable) source of water for the shower, and a separate potable source for the bathroom/kitchen sinks that will be on a separate 3rd Rheem 6kW heater.
Thanks!
